> I was just wondering if anyone has any clever way of testing their backups
taken with pg_dump on a daily basis?
I have a daily bash script to backup of one of my databases to file, then
file to tape, which I test restore once per week. I've changed some of my
variables to hard-coded strings to make it shorter and easier to understand
at a quick read. Yes I know it's kinda fschked but it's working atm. I'll
tidy it up eventually....

if [ "$DAY" = "Mon" ] ; then
	echo "Test restoring database..." >> $LOG_FILE

	if [ 1 -eq 1 ] ; then
		# Debugging
		$ECHO "Restoring from:           ${BACKUP_PATH}"
		$ECHO "Restoring to Directory:   ${TMPDNAME}"
		$ECHO "Restore Database:         ${DBNAME}${DATESTRING}"
		$ECHO "Restore Source File:      ${TMPFILE}"

	echo -n "Extracting database dump from tape... "
	tar xf /dev/st0 --directory /tmp
	if [ $? -ne 0 ] ; then
		echo "FAIL"
		echo "   Failed to Restore from /dev/st0 to /tmp/" >>

	if [ ${SHOW_ERR} != true ] ; then
		### Note: $DATESTRING = yymmdd (eg. 080519)
		echo "Creating new database ${DBNAME}${DATESTRING}" >>
		/usr/local/bin/psql --command "CREATE DATABASE
		if [ $? -eq 0 ] ; then
			echo "Restoring /tmp/psqldump.sql.502 to
			/usr/local/bin/psql ${DBNAME}${DATESTRING} <
			echo "Failed to Create Database!" >> $LOG_FILE

> su - $PGUSER -c "pg_restore -h localhost -U postgres --disable-triggers -c
-d $database $backup_dir/$server-$database-data.gz" >> $logfile
> or 
> su - $PGUSER -c "pg_restore -h localhost -U postgres --disable-triggers -c
-d $database $backup_dir/$server-$database-data.gz >> $logfile"

Perhaps something like this: (it's Monday morning, so I might be suggesting
something stupid)
LOG=`su - $PGUSER -c "pg_restore -h localhost -U postgres --disable-triggers
-c -d $database $backup_dir/$server-$database-data.gz"`
echo $LOG >> $logfile
